Basic Molten Salt Route to Prepare Porous SrTiO3 Nanocrystals for Efficient Photocatalytic Hydrogen Production

“…The crystallization of the ions at the near sites instead of the thermodynamically advantageous positions may be responsible for the formation of cellular surfaces. The growth is similar to the Volmer-Weber (VW) mode, [23] and possible ripening processes are prevented by the low temperature and the high solution viscosity. At this point, kinetics dominates the crystal growth.…”

Time-resolved photoelectron spectroscopy of low-energy excitations of 4×4 C60/Cu(111)

“…In photoemission one photon is applied onto the sample and an emitted electron can be detected [84][85][86]. For the interpretation of PE experiments on condensed matter the three-step model by Berglund and Spicer [87,88] has proven to be useful.…”

Quantum mechanics of rectilinear orbits of the Coulomb-Kepler problem

“…(3-72) in [4]. Rutherford backscattering spectrometry (RBS) is a widely used analytical tool in the sciences [10]; for recent works see for instance: in solid state and surface physics [16,5], in earth science [3], in astrophysics [6], or in archaeology [9]. As compared to scattering theory which is concerned with asymptotic states, here we start with a wave function which is prepared at time t = 0 for a finite distance and can be continuously followed for t > 0.…”
